Purpose: Buried penis is defined as a normal-sized penis hidden below the surface of subcutaneous tissues. The penis might be partially visible or completely invisible with glans covered by prepuce. The etiology may arise from incorrect anchoring of the superficial fascia and skin to the deep fascia at the base of the penis. The goal of this study is to evaluate the outcomes of deep fascia YV scrotoplasty in correcting buried penis in children.

Materials and Methods: A total of 23 patients was enrolled, age ranged from 4.2 years to 16.2 years with median 12.1 years and BMI from 15.4 to 29.4 kg/m^2. Of the 23 patients 12 was incomplete type. Besides of buried penis, 1 was associated with VACTER, 2 with spinal bifida, 3 with hypospadias, 1 with trapped penis and 1 with hydrocele. Initially deep fascia YV scrotoplasty was performed to fix at penoscrotal level after ventral longitudinal incision to relieve dartous fascia tethering and finally complete to remove redundant prepuce.

Results: Post operation voiding with difficulty occurred in 2 cases initially. The rest of 21 cases were with smooth.courses. Penile length increased from 2 cm to 3.5 cm in 7 cases with a mean 2.64 cm. The shape of penis was glans exposed and penoscrotal angle retained. The period of follow-up ranged from 1 week to 18 months.

Conclusions: Deep fascia YV scrotoplasty can demonstrate good cosmetic outcome in correcting buried penis in children.
